Frequently asked questions
How do I scan a product?
Open the center Scan tab and point your camera at a barcode. Tanu looks up the product
and shows its price history in a second.
What does the price verdict mean?
Tanu normalizes each price to a unit price (per kg or per litre) and compares it to the
community price history: good deal, average, or
expensive.
Where do the prices come from?
Prices are shared by the Tanu community. When you add a price you saw in store, it helps
everyone else compare — and their prices help you.
Can I edit or delete something I added?
Yes. You can edit or delete any product or price you created. You can't change entries
added by other users, to keep community data trustworthy.
Where does nutrition info come from?
From Open Food Facts — Nutri-Score, NOVA group, additives, allergens, and diet labels,
shown on the product detail screen when available.
How do I remove ads?
Upgrade to the premium plan from your account screen. Premium removes every ad in the
app.
Which languages and currencies are supported?
Five languages (French, English, Spanish, German, Italian) and multiple currencies. Tanu
is France-first, so French is the default.
How do I delete my account?
Send an account deletion request from the in-app Feedback screen. We'll remove your
account and the personal data linked to it.
Still stuck?
